Presence of Fragmented QRS Complexes in Patients with Obstructive Sleep Apnea Syndrome.

Background: Obstructive sleep apnea syndrome (OSAS) is a disease with increasing prevalence, which is mainly characterized by increased cardiopulmonary mortality and morbidity. It is well-known that OSAS patients have increased prevalence of cardiovascular diseases including coronary heart disease, heart failure, and arrhythmias. The aim of this study was to evaluate the presence of prolonged and fragmented QRS complexes, which have previously been associated with cardiovascular mortality, in OSAS patients.

The effect of hemodialysis on electrocardiographic parameters.

Background: Cardiovascular complications are the leading causes of premature deaths in hemodialysis patients. Due to rapid changes in volume and electrolyte concentration following dialysis, the some electrocardiographic (ECG) changes or arrhythmias might be seen.

Objective: To investigate the acute effects of hemodialysis on the ECG parameters in patients with chronic end-stage renal disease (ESRD).

Assessment of left atrial mechanical functions in thyroid dysfunction.

Introduction:  Thyroid hormone deficiency can lead to the impairment of cardiac function.

Objectives:  The aim of the study was to determine the left atrial (LA) mechanical function in patients with subclinical hypothyroidism (SHT) and overt hypothyroidism (OHT) and investigate associations of LA mechanical function with diastolic function. 

Patients And Methods:  Twenty‑six patients with newly diagnosed SHT (mean age, 42.

Plateletcrit and red cell distribution width are independent predictors of the slow coronary flow phenomenon.

Background And Purpose: Endothelial dysfunction may play a role in the pathogenesis of the slow coronary flow (SCF) phenomenon. A detailed examination of blood cellular components has not been performed for this condition. We investigated the relationship between SCF and whole blood cell counts.

Assessment of QRS duration and presence of fragmented QRS in patients with Behçet's disease.

Background: QRS prolongation and the presence of QRS fragmentation in 12-lead ECG are associated with increased mortality and sudden cardiac death in the long term. In this study we aimed to assess QRS duration and fragmentation in patients with Behçet's disease (BD).

Methods: A total of 50 patients (mean age 42.

Usefulness of monocyte chemoattractant protein-1 to predict no-reflow and three-year mortality in patients with ST-segment elevation myocardial infarction undergoing primary percutaneous coronary intervention.

Although monocyte chemoattractant protein-1 (MCP-1) levels are increased in patients with ST-segment elevation myocardial infarction, the prognostic value of MCP-1 in primary percutaneous coronary intervention (pPCI) is not clear. The goal of the present study was to investigate the association of MCP-1 levels with myocardial perfusion and prognosis in patients with ST-segment elevation myocardial infarction undergoing pPCI. Consecutive pPCI patients (n = 192) were assigned to tertiles according to their admission serum MCP-1 levels.

Atypical type of dual left anterior descending coronary artery.

Dual left anterior descending coronary artery (LAD) is a rare coronary anomaly and is divided into six subgroups in the literature according to the origin and course of the short and long branches of the anomalous artery. We present two distinct cases of dual LAD which are distinguished by two branches of equal length from their counterparts in the literature. < In our cases a novel dual LAD variant is presented with two main branches of equal length and reaches the cardiac apex.

Differences in sex, angiographic frequency, and parameters in patients with coronary artery anomalies: single-center screening of 25 368 patients by coronary angiography.

Background: Although the prevalence of coronary artery anomalies varies in different series, the precise population frequency is unknown.

Materials And Methods: The medical records of all patients who underwent coronary angiography between January 2002 and August 2012 were retrieved, and 238 cases with coronary anomalies were evaluated. Unlike other studies, we compared several angiographic parameters (fluoroscopy time, number of images, and catheters used) in addition to frequency and sex data.

Large caseous mitral annular calcification with mitral stenosis, dynamic left ventricular outflow obstruction, and syncope.

Can aortic elastic parameters be used for the diagnosis of volume overload in patients with end stage renal disease.

Background: We aimed here to investigate hydration status by echocardiography in end stage renal disease (ESRD) patients.

Methods: 25 ESRD patients [15 males; mean age: 54.0±16.

Left main coronary artery thrombus resulting from combined protein C and S deficiency.

Inherited hypercoagulopathies such as protein C and S deficiency usually lead to the formation of venous thrombi in clinical practice; however, they rarely lead to arterial thrombosis. It has been demonstrated that both protein C and S deficiency may lead to myocardial infarctions. However, our literature review revealed no reports of left main coronary artery thrombi caused by protein C and S deficiency.

Severe main coronary artery disease in a young woman with ankylosing spondylitis.

Patients with ankylosing spondylitis (AS) have an approximately two-fold increased death rate compared to the general population, which is predominately caused by increased cardiovascular risk. The prevalence rate for myocardial infarction is approximately 2-3 fold increased as compared with the general population. The inflammatory process appears to have an important role in causing this excess cardiovascular risk.

Pigtail catheter fracture and embolization into the abdominal aorta: an extremely rare angiographic complication.

Coronary angiography is a widely used diagnostic method for coronary artery disease. In clinical practice, although complications of the procedure often involve the vascular access point, there is no previous report of the fracture and embolization of the distal tip of a pigtail catheter. Herein, we present the case of a 51-year-old woman whose left ventriculography was interrupted by fracture of the curved tip of a pigtail catheter, which remained at the renal artery level in the abdominal aorta.

Evaluation of biochemical, hematological, and thyroid function parameters in nondipper and dipper hypertensive patients.

Aim Of The Study: In this study we investigated the effects of biochemical, hematologic, and thyroid function parameters on the circadian rhythm of hypertensive patients whose 24-h ambulatory blood pressure was being followed.

Methods: We studied the fasting glucose, urea, creatinine, uric acid, aspartate transaminase, alanine aminotransferase, gamma-glutamyl transferase, total protein, albumin, lipid profiles, sodium, potassium, hemoglobin, white blood cell count, platelet count, mean platelet volume, thyroid stimulating hormone, free thyroid hormone values obtained simultaneously with 24-h ambulatory blood pressure results, as documented in the case records of 470 patients.

Patients: Of the patients, 398 were in the nondipper hypertensive group and 72 in the dipper hypertensive group.

An asymptomatic needle in the left ventricular anterolateral wall: a prison inmate's strange radio antenna.

A foreign body such as a needle in the heart can be life-threatening. While this may occur accidentally, needles may be inserted into the body by psychiatric patients or in cases involving domestic violence. A needle can migrate through the thorax toward the heart.

A case of acute myocardial infarction due to the use of cayenne pepper pills.

The use of weight loss pills containing cayenne pepper has ever been increasing. The main component of cayenne pepper pills is capsaicin. There are conflicting data about the effects of capsaicin on the cardiovascular system.
